This is quite a big deal for the Amiga world - and proves that, in my view, AROS has more of a future than AmigaOS will ever have: it's portable, and it's open source, so experiments like this are more likely to happen.

The AmigaOS is a strange beast, and many design decisions made in the early 80's to implement preemptive multitasking, never took into account of more than one CPU. Big locks, shared OS structures and a very fine grained strict task priority scheduler are just some of the problems that need to be solved without breaking compatibility with older software

This would bring AmigaOS experience to be able to fully utilize modern multiprocessor hardware.

I remember a long time ago, the IT department where I worked was doing an evaluation with a side-by-side comparison of Windows 3.11WFW, OS/2 Warp 3.0, and AmigaOS. The only reason AmigaOS was on this short list was that the VP in charge was using it at home and preferred it over the office stuff! Anyways, the winner was somewhat predictable (Windows).
